RE: 2000 Lincoln LS: After being driven on a hot day, the engine starts but RPM quickly drops to zero after repeated attempts. On cooler days..no problems. The computer wiring harness has been replaced....any further thoughts??? Dan xxxxxxxx XXX@XXXXXX.XXX

see previous note
Are you able to keep it running with the accelerator?
Yes at rapid RPM's
So in lower Rpms even though you are on the accelerator it will still die correct?
Is there a check engine light
You may try cleaning the IAC it is at the back of the engine on the left side i believe. If you have a multimeter we need to test the resistance on this part with the plug to it unplugged.
the resistance should be between 6 and 13 ohms
It is on the intake held on by 10mm bolts.
Remove the plastic engine cover. Locate the IAC valve right next to the TPS.
Squeeze the fitting on the two hoses and pull them off.
Remove the two bolts and the IAC valve. You can clean this valve with rubbing alcohol and it may help. If it helps but the problem still shows back up replace the valve.
Thanks, but this procedure is "above my pay grade" will ask my dealer to look at this. DM
